It's not necessarily corporate, but mainly due to the fact that AI tools are quite new and we're just learning to use them efficiently.
One example is that recently I used the superpowers claude code plugin. I thought it was good because it was popular on github (with 296k stars). However, for a small feature change it basically created 4 different plans and launched 4 agents to work in parallel (write code, write tests, update docs, etc) and then once all 4 sub agents are done it launched another agent to verify the work of all 4 sub agents. It ended up burning so much tokens and taking actually longer to finish and just could have been done without any agent. I immediately uninstall the plugin. These are the kind of things that developers try out that ends up increasing the costs
